humm, the gcc-2.7.2 patch from ftp.linux.sgi.com has a bit more
defined.

well, the 2.7.2 one seems to work.  i just did a make bootstrap w/o too
much dancing.  the one thing that seemed to help quite a but was doing a
'./configure --host=mips-unknown-linux-gnuelf' the elf seems very
important.

no comment.

So, i can get it to build ok now.  But, it fails miserably when trying
to compile collect2.  If i just comment out all of the collect stuff in
the makefiles, it completes the make bootstrap.  

since i'm using gnu binutils, am i going to have all sorts of problems
from skipping this step - or does gnu ld take care of this?? it does get
built on the stage1/xgcc build pass so the final gcc is passwd through
collect2...

and provided it's ok to skip the collect2 stage on the first step in the
make bootstrap, what should i be editing?  i can roughly see how to skip
it entirely, but not just on stage0...  (yes, it's likely a problem w/
gcc-2.7.2 on mips, but it's a real enough problem.)

thanks.  i'll send a patch that cleans up mips-gnuelf support as soon as
i sort out this collect2 stuff.
